So then why not tow at 35 MPH? Even more safe and better fuel mileage.
That is not always true. I can get better gas (diesel) mileage at higher speeds (62-63) than I can at some significantly slower speeds.
It is also important to have the right TV for the trailer you pull. For example, with old Trailmanor I use to have if I had pulled it with a V8 instead of a V6, I would have gotten a much better MPG.
Same thing is true for one of the posters here who is getting the same mileage pulling a TT 3,000-4,000 lighter than mine. Granted my price per gallon is about 10% higher, I am pulling almost two of his trailers.
But I went through two trailers and three trucks to learn that lesson...
